Domestic employee relocation is relatively straight forward in terms of communication, even in countries that span multiple time-zones, like the USA.

However, international relocation can be a completely different kettle of fish. You might be tempted to think that a relocation from Germany to the UK wouldn't throw up too many communication challenges, but what happens at 6PM when the employee in Germany needs to get hold of the UK-based HR or relocation team? Well, it's 5PM in the UK and the majority of folk are heading home. That query will just have to wait until the following morning, regardless of how important it may be.
